Neco Model Questions Vol1 2024 Biology Question 47
Practice objective / multiple choice question 47 from the 2024 Neco Model Questions Vol1 Biology examination.
In a plant cell the water potential is \(-0.3\) MPa. The cell's pressure potential is \(0.2\) MPa. The external solution has a solute potential of \(-0.5\) MPa and negligible pressure potential. (i) State the direction of net water movement. (ii) If the solute potential of the external solution is given by \(\psi_s = -i C R T\) with \(i=1\), \(R = 0.0831\) L·MPa·K\(^{-1}\)·mol\(^{-1}\) and temperature \(T = 298\) K, calculate the solute concentration \(C\) (in mol L\(^{-1}\)) to three significant figures.
